Daniel Friebe: In the last twenty minutes we've heard that Riccardo Riccò has tested positive for an EPO-like product. The early reports suggest that Riccò used CERA or Micera. a so-called third generation EPO. What's your reaction?

Michel Audran: Wow. I'm stunned. I'm amazed they're saying it's Micera, simply because there's no validated test for that yet. The World Anti-Doping Agency is working on a test, but it certainly doesn't exist yet.

DF: What exactly is CERA, or Micera to give it its commercial name?

MA:It's a delayed-action EPO, which has a different molecular mass from EPO. It's only been commercially available since the start of the year. We can tell when someone's used it but we can't declare them positive. In that respect it's like Dynepo, another EPO-like product. We know that Micera was being used on the Giro, so I'm not surprised that it's also turned up at the Tour. But I would be very surprised if they AFLD had declared Riccò positive for Micera, for the reasons I've just mentioned. Maybe they searched Riccò's room and found the product itself...
